Let the number of students in a class be x.

According to question,

Number of student = money donated by each of the students

So total money donated = x ^{2}

or                      x ^{2} = 2401

Prime factorization of       2401 = 7\times7\times7\times7 = (7\times7)^{2} = 49^{2} = x^2

So the number of students in the class = 49.
